WAVE MOTOR.

Application filed December The object of my said invention is to.improvewave motors of the vertically guided iioat type by the provision ofsimple and highly e'iicient means for converting the reciprocate ymotion of a float actuated by waves in a body of water, into a rotarymotion.

To the attainment of the foregoing, the invention consists in theimprovement as hereinafter described and definitely claimed.

In the accompanying drawings, forming part of this speciiicatiom- Figure1 is a side elevation of the wave motor constituting the Vpreferredembodinient of my invention.

Figure 2 is an end elevation of the motor.

Figure 3 is a top plan view of the motor.

Figure 4 is a horizontal section taken in the plane indicated by theline 4-4 of Figure 1, lookingdownwardly.

Similar numerals of reference designate corresponding parts in all ofthe views of the drawings. Y

Among other elements my novel motor comprises a main frame adapted to befixed in a body of water and including uprights 1 of angular form inhorizontal section, and a platform 2 superimposed upon and fixed to theupper ends of the said uprights. The said main frame also comprises ahorizontal bar 3 interposed between and fixed to the uprights 1 at oneend of the frame.

Arranged between and loosely fitting in the uprights 1 is a movableiioat 4 on which are end anti-friction wheels 5 and side antifrictionwheels 6, the said wheels 5 and 6 being arranged to bear against thevertical edges of the uprights 1 of angular form in cross-section so asto render easy the up and down movements of the iioat and to preventundue wear of the oat and uprights 1 incident to the movements of thefloat. y

Appropriately fixed to and rising from the iioat 4 is a standard 7 andpivotally connected to the said standard, and prefer- Y ably capable ofadjustment in virtue of its 3, 1922, Serial No. 608,691.

walking beam 10 is adapted to be adjustably positioned to betteraccommodate the working parts of the mechanism to the size of the wavesin which the float 4 is disposed.

Mounted on the platform 2 is a shaft 13 to which is fixed a ratchetwheel 14. The said ratchet wheel 14 is opposed to a `dog 15 designed toprevent retrograde rotation of the said shaft 13, the said dog 15 beingbacked by a spring strip 15X of considerable length, supported on aninclined pillar block 1G, and appropriately fixed at its outer end 17thereto. Pivoted to the shaft 13 and straddling the ratchet wheel 14 isa lever 13 by which is carried a spring pressed detent 19, arranged onmovement of the lever 18 in one direction, downwardly or upwardly, toturn the ratchet wheel 14 and the c'haft 13, and also arranged to rideidly over the teeth of the ratchet wheel 14 on reverse motion of lever18. Interposed `be tween and pivotally connected to the lever 18 and theouter arm of the walking beam 10 is a link 20. Manifestly when the float4 is moved upwardly and downwardly by the action of waves and gravity,the walking beam 10 will be powerfully rocked or oscillated with theresult that considerable leverage will be exerted on the shaft 13, andsaid shaft will be powerfully turned step by step in one direction.

Any preferred means may be employed for taking power from the shaft 13,the means illustrated for said purpose being made up of a pulley 21fixed on the shaft, a counter-shaft 22 on the platform 2 and equippedwith a pulley 23, and a belt 24 n'iounted on. and connecting the pulleys21 Aand 23.

Itwvill be apparentfrom the foregoing that my novel wave motor is atonce simple in construction and reliable in operation; also, that thewave motor is free from delicate parts and is therefore well adapted towithstand the rough usuage to which wave motors are ordinarilysubjected.

I have entered into a detailed description of the construction andrelative arrangement of the parts embraced in the present and preferredembodiment of my invention in order to impart a full, clear and exactunderstanding of the said embodiment. I do not desire, however, to beunderstood as confining myself to the specific construction and relativearrangement of parts inasmuch as in the future practice of the inventionvarious changed and modifications may be made such as fall within thescope of my invention as defined in my appended claim.

Having described my invention what I claim and desire vto secure byLetters Patent,

A wave motor comprising a plurality of spaced up-rights, a platformmounted upon the 11p-rights, a power ehaft supported upon the platform,horizontal bar between certain of the 11p-rights, a movable ioat withinthe tip-rights, a vertical standard carrie'dfb'y the io'at, a linkhaving its lower end adjustably connected with the standard, a walkingbeam adjustably and pivotally mounted upon the horizontal bar with itsinner' end pivotally connected with the up per end of the link, a leverhaving one end rection upon downward movement of they lever, a spring`pressed dogretaining said ratchet against movement, and a second linkforming loose connection between the outer end; of the lever and theouter end of the walking; beam whereby vertical movement ot' the floatbetween the up-rights in one direction will impart movement to saidshaft.
